CELAENAE, an ancient city of Phrygia, situated on the great trade route to the East. It was the starting point of the march of Cyrus (401 B.e.) with the 1o,000 against Artaxerxes. Its acropolis long held out against Alexander in 333 and surren dered to him at last by arrangement. Antigonus made it the capi tal of his kingdom ; Antiochus of Syria, the son of Seleucus re founded it on a more open site as Apameia (q.v.) . West of the acropolis were the palace of Xerxes and the Agora, in or near which is the cavern whence the Marsyas, one of the sources of the Maeander, issues.
